Dear list, running a hierachical cluster analysis I want to define a number of objects that build a cluster already. In other words: I want to force some of the cases to be in the same cluster from the start of the algorithm. Any hints? Thanks in advance! Derik [[alternative HTML version deleted]]

Thanks in advance!The hclust function has an argument 'members' that should allow you to do that. You will need to specify the dissimilarity matrix accordingly. Peter
